to a resilient handle adapted to be provided foruse in connection withall Varieties of tool and lever handles or other instrument adapted tobe gripped'by the human hand.

As a principal object this invention contemplates, in the provision, ofa handle of the type set forth, the production of adapted to absorb theshocks dent to attached, such grip to be readily adjustable to handlesof diderent sizes andto different and jars incipositions upon any givenhandle as dictated by the comfort erator.

A further and cobrdinate, object is to provide readily removablesecuring means for a shock absorbing grip of the character deandconvenience of the opscribed which shall be removed'from any contactwith the flesh of the users palm and which will directly insure theattainment of a firmer grip than would be otherwise obtainable.

It is an object of equal importance with the foregoing to provide a gripof this sort with oppositely disposed terminal abutments preventingdislodgment of the operators hand therefrom when heavy blows are to bedelivered by the tool or instrument.

A further object of major importance is concerned with the economicaldesign of an auxiliary shock absorbing handle capable of attaining thepreceding objects with facility while at the same time- -cailing for arelay tively low cost of manuf acture. The above and additional objectswhich will become apparent as this explanatory description proceeds, areaccomplished by such means as are illustrated in theaccompanyingdrawings, described in the following specification and then moreparticularly pointed out. in the claims which are append? ed hereto andform a part of this applica-,

reference refer to corresponding parts throughout the several views:Figure 1 illustrates 1n perspective the auxiliary handle of .thisinvention as secured upon an instrument handle (in section) and grippedby the user, Fig. 2 is a longitudinal section through the handle, Fig. 3is a transverse sectional view taken on the plane indicated by the lines3-3 of Fig.2, Fig. ,4 is aplan of the grip blank as spread 5 is asection therethrough on the line 5-5, and Fig. 6 is a View inperspective and similar to Fig. 1 showing the grip assembled.

. The grip comprehended by this invention is of the hollow ovoidal formin cross section shown in Fig. 3 having a relatively greater thicknessat the rounded portions of shorter radius indicated by the numeral 10,the length of the grip being sufiicient to accommodate the entire handof the user. as indicated in' Fig. -1' with the extremities 11 ofgreater diameter than the central portion into which latter' the formergradually merge in presenting that concavity of outline to beparticularly noted in Figs. 2 and 6.

The material made use of is, preferably, rubber of a consistencyaffording a suflicient resilient grip as combined with the quality ofdurability, the entire device being capable of being molded at oneoperation. At the time of such molding there is formed at one extremitythe raised 'arcuate abutment 12 which is'adapted to conform exteriorlyto what may be termed the rounded V produced between the thumb andforefinger of an operators hand when gripping such a handle. Similarlythere is provided upon the opposite portion of theother terminus of'theauxiliary vhandle the abutment 13 which is designed to conform to thatposition assumed by the outer line of the little finger,so-thatdislodgment of a hand pleeeel between these two abutments in grippingtimate user is in the approximately square form shown in theillustration of the blankiin Fig. 4 and having the sectionalconformation shown in Fig. 5 where the points of bending are indicatedbythe numerals 1d and the closure edges by the numerals 15. Spaced fromthese closure edges and in a series parallel thereto are the circularrecesses 16 which are adapted to accommodate the heads 17 of screws 18in the manner clearly shown in Fig. 2, such screws being the retea sincethe edges of these recesses are resiliently distortable for thispurpose. It will thus be seen that-the abutments 1'2 and 13 preventlongitudinal displacement of the users hand while the mentioned vacuumcups 16 tend to prevent a loosening of the gripping action of the hand.Additional recesses 19 are provided for the portion of the handleopposite the closure edges to effect a distribution of the strain uponthe rubber surrounding the screws 18 and to aflord additional suctioncups, screws 20 being accommodated in these added recesses.

From the foregoing it should be apparent that an auxiliary handle gripof the type above set forth is readily capable of attachment uponhandles of various sizes due to the elasticity of the material composingsuch handle grip whereby the closure edges may be stretched toward eachother to assume the contiguous relation desirable, in the case of largerhandles while removal of the screws 18 and 20 will permit the handlegrip to be adjusted to any longitudinal position upon a given tool,instrument or lever handle.

The remainingobjects of this invention, it will be apparent, are alsoreadily attainable, so that this invention may therefore be claimed aspossessing the advantages and desirability set forth in such objects.

While in the foregoing there has been thus illustratedin the drawingsand described in the specification the preferred embodiment of thisinvention, it is desired to emphasize the fact that certain minorchanges in the matters of proportion and degree may be resorted towithout departing from the spirit of the invention as defined in theappended claims.

lVhat is claimed is 1- 1. A handgrip for tool handles, comprising asleeve of relatively elastic compressible material having recessesformed therein with I their outer ends open to serve as vacuum cups.

2. A hand grip for tool handles, comprising a sleeve of relativelyelastic compressible material provided at its ends with abutments andhaving recesses formed therein between the abutments with their outerends open to serve as vacuum cups.

3. A hand grip for tool handles comprising a sleeve of relativelyelastic compressible material provided at its ends with abutmentsextending laterally in opposite directions and having recesses formedtherein between the abutments with their outer ends open to serve asvacuum cups, and attaching elements disposed in the bottom of certain ofthe vacuum cups for securing the sleeve to the handle.

4:. A hand grip for tool handles, comprising a sleeve of relativelyelastic compressible material provided at its ends with abutmentsextending laterally in opposite dircc tions and having oppositelyarranged sets of recesses formed therein between the abutmcnts withtheir outer ends open to serve as vacuum cups, and attaching elementsdisposed in the bottom of certain of the vacuum cups for securing the.sleeve to the handle.

In testimony whereof I atlix my signature in presence of two witnesses.
